PREPARATION
Placing the Speakers
To enjoy quality sounds thoroughly, you need to place the speakers in their appropriate positions and install them
correctly. After deciding the speaker layout, follow the procedure below to install the speakers.
Satellite speakers (L, R) (NX-S30)
Satellite speaker (R)
Satellite speaker (L)
Place the left/right speakers on both sides of your TV at equal
distances. We recommend that you place the speakers at the
height of your ears at the listening position, and keep the speakers
at least 80 cm (2’ 6”) apart while they are placed 80 cm (2’ 6”)
away from the side walls.
Main roles: Produces front channel (stereo) sounds. Also
produces center channel sounds (dialogues or vocal sounds) and
surround channel sounds effectively using the Yamaha Air
Surround system.
Subwoofer (NX-SW30)
Place the subwoofer near a front speaker and turn it slightly
toward the center of the room to reduce wall reflections.
Main roles: Produces bass sounds and low frequency (LFE)
sounds contained in Dolby Digital or DTS.
Subwoofer
Notes
• Be sure to place the satellite speaker (L) on the left of the TV and the satellite speaker (R) on the left of the TV since the speakers are
not symmetrical. Check the (L) and (R) marks printed on the back of each speaker to identify them.
• To create better acoustic field, you need to place the satellite speakers properly and adjust the orientation of the virtual surround
speakers suited for your listening environment. Also, the arrangement of furniture affects the acoustic field. For details, refer to
“Adjusting the Orientation of the Virtual Surround Speakers” (page 16).
• If the speakers interfere with TV reception, noises may appear on the TV screen. In such a case, move the speakers a little away from
the TV.
• Bass sounds produced by the subwoofer may be heard differently depending on the listening position and subwoofer location.
To enjoy desired sounds, try to change the location of the subwoofer according to the listening position.

PREPARATION
■ Placing the Satellite Speakers
You can place the satellite speakers on a rack, or attach them to a wall. Please select an installation method that suits your
room layout.
y
To place on a rack
Non-skid pad
(small)
Attach the non-skid pads (small) to the bottom of
each speaker, and then place them on level hard
surfaces.
y
Using non-skid pads prevents the speakers from sliding when
they vibrate, and ensures quality sound production.
To attach to a wall
198 mm
(7-25/32”)
Diameter of 3.5 to 4 mm
(1/8” to 5/32”)
20 mm (25/32”)
or more
You can attach the speakers to a wall using commercially
available screws (Diameter: 3.5 to 4 mm (1/8” to 5/32”), Length:
24 mm (15/16”) or more). One speaker requires two screws.
1
Install two screws in the wall where you want
to place the speaker.
2
Hang the speaker on the screws using the
holes in the back of the speaker.
4 mm
(5/32”)
198 mm (7-25/32”)
Notes
• One speaker weighs about 1.4 kg (3 lbs 3 oz). To attach a speaker to a wall using screws, the wall must be firm. Do not attach a speaker
to a wall that is made of weak materials such as plaster or veneered woods. Doing so may cause the speaker to fall.
• Make sure you use specified screws to attach a speaker to a wall. Using clamps other than specified screws, such as short screws, nails,
or two-sided tape, may cause the speaker to fall.
• When connecting the speakers, fix the speaker cables in place so that cables do not loosen. If your foot or hand accidentally gets
caught on a loose speaker cable, the speaker may fall.
• After attaching each speaker, check that the speaker is fixed securely. YAMAHA will bear no responsibility for any accidents caused
by improper installations.
■ Placing the subwoofer
Attach the non-skid pads (large) to the bottom of
the subwoofer, and then place the subwoofer on
a level hard floor.
y
Using non-skid pads prevents the subwoofer from sliding when it
vibrates, and ensures quality sound production.
Non-skid pad (large)

PREPARATION
You can attach the satellite speaker to a commercially available speaker bracket or speaker stand using the screw holes on the bottom of
the speakers. In this case, be sure to use 6M (diameter of 6 mm) screws.
PREPARATION
Connecting the Speakers
Follow the procedure below to connect the satellite speakers (NX-S30) and subwoofer (NX-SW30) to the AV amplifier
(AVC-S30).
Notes
• Do not connect the power cables of the AV amplifier and subwoofer until all cable connections are completed.

ADDITIONAL INFORMATION
Glossary
■ Dolby Pro Logic II
Front surround sound system which is developed by
Yamaha enables the surround sound field using six
speaker units built in two satellite speakers. In comparison
with traditional front surround technologies, the Air
Surround system enables a wide range of natural surround
sound field.
It is an improved matrix decoding technology that
provides better spatiality and directionality on Dolby
Surround programmed material; provides a convincing
three-dimensional sound field on conventional stereo
music recordings; and is ideally suited to bring the
surround experience to automotive sound. While
conventional surround programming is fully compatible
with Dolby Surround Pro Logic II decoders, soundtracks
will be able to be encoded specifically to take full
advantage of Pro Logic II playback, including separate left
and right surround channels. (Such material is also
compatible with conventional Pro Logic decoders).
■ Channel (ch)
A channel is an audio type that has been divided based on
range and other characteristics.
Ex. 5.1 channel
• Front speakers, Left (1ch), Right (1ch)
• Center speaker (1 ch)
• Surround speakers, Left (1ch), Right (1ch)
• Subwoofer (1 ch x 0.1* = 0.1 ch)
*
In contrast to a full 1-channel band, a component designed to
enhance low frequency sound for added effect.
■ CINEMA DSP
(Digital Sound Field Processor)
■ DTS (Digital Theater System)
Digital surround sound system developed by Digital
Theater Systems, Inc., which provides 5.1 channel audio.
With an abundance of audio data, it is able to provide
authentic-sounding effects.
■ DVS (Dolby Virtual Speaker)
Since the Dolby Surround and DTS systems were
originally designed for use in movie theaters, their effect
is best felt in a theater having many speakers and designed
for acoustic effects. Since home conditions, such as room
size, wall material, number of speakers, and so on, can
differ so widely, it’s inevitable that there are differences in
the sound heard as well. Based on a wealth of actually
measured data, YAMAHA CINEMA DSP uses
YAMAHA original sound field technology to combine
Dolby Pro Logic, Dolby Digital and DTS systems to
provide the visual and audio experience of movie theater
in the listening room of your own home.
Front surround sound system which is developed by
Dolby Laboratories provides 5.1-channel audio.
■ Dolby Digital
The number of sampling (process for digitalizing analog
signals) per second. In principle, the higher the sampling
rate, the wider the frequency range that can be played
back, and the higher the quantized bit rate, the finer the
sound that can be reproduced.
Digital surround sound system which is developed by
Dolby Laboratories provides completely independent
multi-channel audio. With 3 front channels (left, center,
and right) and 2 surround stereo channels, Dolby Digital
provides five full-range audio channels. With an additional
channel especially for bass effects (called LFE, or low
frequency effect), the system has a total of 5.1-channels
(LFE is counted as 0.1 channel). By using 2-channel
stereo for the surround speakers, more accurate moving
sound effects and surround sound environment are
possible than with Dolby Surround.
■ PCM (Pulse Code Modulation)
A signal that is changed to digital format without
compression. A CD is recorded with 16-bit sound at 44.1
kHz, while DVD recording is anywhere from 16 bits at 48
kHz to 24 bits at 192 kHz, which makes it a higher quality
sound than CD. This signal also has a type called Packed
PCM (PPCM) that can be compressed without any loss of
data.
■ Sampling frequency
■ “SILENT CINEMA”
“SILENT CINEMA” was developed by YAMAHA as a
natural, realistic sound effect DSP algorithm for
headphones. Parameters for headphones have been set for
each sound field so that accurate representations of all the
sound field programs can be enjoyed on headphones.
